Application filed September 9,1919, Serial No. 322,654.

To all whom t may concern: 7

lie it known that I, NELSON B. HENRY, a citizen of the United States, residin at Atlanta, in the county of Fulton and gtate of Georgia, have invented certain newand pressing Oil from Cotton and'Similar Seed Meats, of which the following is a specification. i

My inyention has relation to an apparatus for the expressing of oil from cotton and similar seed meats and in such connection it relates more particularly to the arrangement and construction of; the apparatuswhereby the cake is evenly and economically formed and accurately and lirectly' fed from the cake forming means to' and stacked in an expresslng cage.

Heretofore in the generally used type of oil press, the formed cakes when removed from the cake forming means and wrapped in their cloths by hand, are'removed by hand and stacked in a press by hand. The cakes are improperly shaped and their stacking in thepress is awkward and inaccurate for the full expressing of the oil.

In this my present application for patent, I have shown and described and will hereafter claim, a cake forming means comprisin; a cake shaping die arranged to be re ciprocated between three positions one below the discharge from the cooker, a'second beyond the cooker and the third belowa plungerand in registration with the cake re ceiving cage ofa press, whereby upon the operation of the plunger the cakes are consecutively forced from the die into and downwardly in the cage until said cage is filledQ The present application has 'there fore relation tot-he cake forming and stacking means, other portions of the machinery and apparatusrequired being illustrated in companion applications for patent."

The nature and scope of my ihyention will be more fully understood from'the following description taken in connection with the accompanying drawings forming part hereof, in which Figure 1 is a side elevation of an oil press embodying the main features of my inven tion, the cooker and cake forming die being shown in dotted lines.

Figure 2 is a top or plan view of the press.

Figure 3 is a side elevational view partly sectioned of the cooker and cake forming m n Figure 4 is a plan view of the reciprocating frame and cake-forming die, and

Figure 5 is a detail of the hydraulically operated piston for operating tne frame and die.

Referring to the drawings, 1 is a cooker of any preferred type of construction and 2 is the discharge outlet therefrom. Arranged below the outlet 2 and in close proximity thereto is a sliding table 3, carrying at its left hand end, a cake-shaping die 4. The table 3, with its die 4 is carried upon a Way or table 5, and is arranged to be moved thereon into either of the required positions by means of a power mechanism. I have shown in the drawings a cylinder and piston 6, operated by any suitable fluid, the stemor rod 6 of which is connected with the right hand endlof table 3. The three positions required inthe mechanism shown are,.tirst, position betwen the plunger 10 and the cooker outlet 2, in which the lower covering 8 of the cake is placed in position in the-die, and supported by the way or table 5 (see 3); second, a position beneath the cooker outlet 2, in which the die is filled with cooked seed. the outlet being progressively opened as the table 3 is shifted to the right, the seed being retained in the die by the cover 8 supported the table or way 5; third, a shift back tothe first position, in which position the top covering 8 is applied to the cake, the cooker outlet being progressively closed, as the die is moved, by the table 8 (see Fig. 3); fourth, a position in which the die is brought beneath the plunger 10,'the die passing be nd the table 5 and over the cage 77 with its contained following block or cakes, in readiness to be operated upon by the plunger 10. The die 4: preferably has its corners 4 rounded in order that the cooked meats may fill out the entire chamber of the die.

When the die with the covered cake is moved'so thatits chamber 'registers withthe interior of the cage 77 inpress 7, said interior of the cage being of an area and outline corresponding to of the chamber of said die 4, the plunger 10, actuated by piston 9, moves downward to compact the cake and force it into the cage. The piston 9 is now withdrawn to lift the plunger 10 out of the die and said die is quence ot steps above described is repeated in .ii the cage in press 7 is filled with cakes. in the sequence of steps the cookerdischarge opening is at all times closed except when the die 4: is below the cooker opening the means shown beino: the table also the bottom covering oi the cake, placed in the die, is at all times supported, the means shown being either the table 5 or the contents of the cage, when the die is beneath the plunger The filled is removed from press 7 and placed in the oil. expressing press, not shown. 2

The press 7 is provided at its base with a hydraulic piston 12 which when operated orces a block 13 upwardsin the cage to dis lodge the cakes after the oil has been ez trac-ted therefrom. This block 13 acts as a follow up block in the stacking of thecakes the chain of the cage as they are forced out of the forming die 4 by plunger 10 as follows: When the first cake is brought under plunger 10. the follow block 13 is flush or level with the top of the press cage and with the bottom of the cake forniiug die. As the plunger 10 is operated to force the cake out of die 4 into the cage, its movement is transmitted to follow block 13 causing the same to yield corresponding distance. The hydraulic fluid displaced in press cylinder 13 during this yielding movement of block 13 and piston escapes through a relief valve 13 As successive cakes are stacked in the cage, the last cake above block 13 is on a level with the top of the cane and flush with the bottom of the cake forming die, and block 13 is successively forcec down the required distance in the manner above set forth. By suitable regulation of relief valve 13 the density of the cake packed in the cage canbe accurately established. This accuracy is desirable for the reason that it the density of the packed cake in such cage is made uniform the succeeding expressing operation is facilitated and the highest percentage of oil extraction is secured. The follow up block 13 with its regulatable relief valve 13 therefore acts as a resistance means for compressing each cake in the cage thus permittingof the reception ot-a maximum number of cakes in said cage. 7 To permit of the vdislodgment of the cakes, the upper piston 11 and plunger 10 are so arranged as to be swung backward on the top ot the press to clear the top of the cage. iVhilc many arrangements of the upper piston and plunger may be made to permit ot the clear: ance or uncovering oi"- the top of the press 7, the arrangement shown in the drawing is preferred. In this instance the cylinder 14 for the piston 1. is supported by a relat-ively heavy base 15 and this base is hinged at one side as at 16 to a top frame 17 for press 7., The other side of the base is provided with a lug 1S fitting under hinged frame 19 carrying a locking bolt 20.

. When bolt 20 is retracted from the lug 18, the frame 19 may be swung to clear the lug 18, and the cylinder 14- with its base 15 may be swung on its hinges 16 to clear the top of press 7. It is to be understood that the inlet and outlet pipes 21. 22 and valve 23. controlling said pipes, swing with the cylinder and base, the pipes 21, 22 having suitable swivel connection with the stationary fluid pipes 2 l25 which are supported by and traverse that part of hinge connection 16 which is part of or supported by the top frame 17 for press 7.

Having thus described the nature and ob jects of my invention, what I claim as new and desire to secure by Letters Patent is- 1. In an apparatus of the character described, an open-ended die, formed in a die table; a second table on which the die table slides in a straight path; a cage, operatively arranged in the path of the die; a cake-forming plunger path of the die, a yielding resistance plunger moving through the cage and beneath the cake-forming plunger to react against the cake forming plunger in. compacting the cake. 1

2. Inan apparatus of the character dc scribed, an open-ended die, formed in a die table; a second table on which the die table slides in a straight path; a cage, operatively arranged. in the path or the die; a cake form plunger above the cage and over the path of the die, a. yielding resistance plunger, operating within the cage, and hav ing a plunger cylinder; a relief valve connected to that plunger cylinder; the resistance plunger 1 reacting against the cake formingplunger in compacting the cake.

' In testimon whereof I have si ned mv name to this specification.
